Description

Technical Field

[0001] This utility model relates to the field of slitting machine winding, specifically a winding mechanism for a center surface winding slitting machine. Background Technology

[0002] In the processing of materials such as metal foil, plastic film, and paper, the center surface winding slitting machine is used to cut wide materials into multiple narrow strips and simultaneously perform winding operations.

[0003] The existing winding mechanism drives the winding roller to rotate via a motor. As the winding roller rotates, the material is gradually and tightly wound onto the winding roller, which can ensure that the slit material is wound up evenly.

[0004] However, in order to facilitate the removal of the material wound on the take-up roller, the take-up roller is usually exposed. When working in the factory area, it is very easy for foreign objects to touch the take-up roller, which can cause the wound material to become skewed, resulting in the material not being neatly wound. Moreover, when winding up the slit material, due to the different thicknesses and materials, loosening may occur during the winding process, which will directly lead to uneven tension, resulting in winding defects and thus reducing the quality of winding. Utility Model Content

[0005] The purpose of this invention is to provide a winding mechanism for a center surface winding and slitting machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a winding mechanism for a center surface winding and slitting machine, comprising: a base plate, two symmetrically arranged mounting brackets fixedly mounted on the upper surface of the base plate, a fixed seat fixedly mounted on the side wall of the mounting bracket, a stud fixedly mounted on the outer side of the fixed seat, a rotating disk sleeved on the outer surface of the stud, a fastener threaded to the top of the stud, and a pressure roller rotatably mounted on the inner side of the rotating disk;

[0007] The mounting bracket has a mounting groove on the inner side of its top end, a mounting block on the inner surface of the mounting groove, a protective baffle fixedly mounted on the side surface of the mounting block, a sliding rod fixedly mounted on the lower surface of the top end of the mounting bracket, a limiting block sleeved on the bottom end of the sliding rod, and a spring sleeved at the connection between the outer surface of the sliding rod and the limiting block.

[0008] Preferably, the mounting bracket has an inner cavity, a slide rail is fixedly installed on the side wall of the inner cavity, and a threaded hole is opened at the top of the mounting bracket.

[0009] Preferably, a mounting base is slidably mounted on the surface of the inner cavity, and a groove is formed on the side wall of the mounting base.

[0010] Preferably, a screw is fixedly mounted on the upper surface of the mounting base, and the screw is threadedly connected to a threaded hole.

[0011] Preferably, the mounting base slides on the surface of the inner cavity through the sliding engagement of the screw and the slide groove and slide rail.

[0012] Preferably, a motor is fixedly mounted on the outer side of the mounting base, and a take-up roller is rotatably mounted on the output end of the motor.

[0013] Preferably, the stud has an internal thread at its top and an external thread inside the fastener. The fastener limits the rotation of the rotating disk through the threaded engagement of the external thread and the internal thread.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model proposes a winding mechanism for a center surface winding and slitting machine;

[0016] 1. By loosening the fasteners, the rotating disc can be rotated on the side wall of the fixed seat via the stud, thereby adjusting the angle of the pressure roller. The external thread inside the fastener engages with the internal thread at the top of the stud to fix the adjusted angle of the pressure roller. This allows it to adapt to materials of different thicknesses and materials, and can closely adhere to the surface of the material, ensuring uniform winding, reducing loosening during winding, and avoiding winding defects caused by uneven tension, thereby improving product quality.

[0017] 2. The protective baffle can prevent the winding roller from being touched by foreign objects, thus improving the safety of the winding operation. By pushing the limit block upward, the limit block compresses the spring on the sliding rod, thereby releasing the installation limit of the protective baffle. This allows the mounting blocks on both sides of the top of the protective baffle to be removed through the mounting slot, making it easier to remove the protective baffle when unloading the winding roller and improving convenience.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 7 This utility model provides a technical solution: a winding mechanism for a center surface winding and slitting machine;

[0028] Example 1:

[0029] To allow for adjustment of the angle of the pressure roller 8, a fixed seat 4 is fixedly installed on the side wall of the mounting frame 2. A stud 5 is fixedly installed on the outer side of the fixed seat 4. A rotating disk 6 is fitted onto the outer surface of the stud 5. A fastener 7 is threadedly connected to the top of the stud 5. The pressure roller 8 is rotatably mounted on the inner side of the rotating disk 6. The top of the stud 5 has an internal thread, and the inside of the fastener 7 has an external thread. The fastener 7 limits the rotation disk 6 through the threaded engagement of the external and internal threads. By loosening the fastener 7, the rotating disk 6 can rotate on the side wall of the fixed seat 4 via the stud 5, thereby adjusting the angle of the pressure roller 8. The adjusted angle of the pressure roller 8 can be fixed by the threaded engagement of the external thread inside the fastener 7 and the internal thread at the top of the stud 5.

[0030] Example 2:

[0031] To prevent the winding roller 21 from being touched by foreign objects during the winding process, two symmetrically arranged mounting brackets 2 are fixedly installed on the upper surface of the base plate 1. The top inner side of the mounting bracket 2 is provided with a mounting groove 9, and the inner surface of the mounting groove 9 is provided with a mounting block 14. A protective baffle 13 is fixedly installed on the side surface of the mounting block 14. The protective baffle 13 can prevent the winding roller 21 from being touched by foreign objects, thereby improving the safety of the winding operation.

[0032] Example 3:

[0033] Based on Embodiment 2, in order to facilitate the removal of the protective baffle 13 when unloading the take-up roller 21, a sliding rod 10 is fixedly installed on the lower surface of the top of the mounting frame 2. A limiting block 12 is sleeved on the bottom end of the sliding rod 10, and a spring 11 is sleeved at the connection between the outer surface of the sliding rod 10 and the limiting block 12. By pushing the limiting block 12 upward, the limiting block 12 compresses the spring 11 on the sliding rod 10, thereby releasing the installation limitation on the protective baffle 13, so that the mounting blocks 14 on both sides of the top of the protective baffle 13 can be removed through the mounting groove 9.

[0034] Working Principle: In actual use, to adjust the angle of the pressure roller 8, the fastener 7 is loosened, allowing the rotating disk 6 to rotate on the side wall of the fixed base 4 via the stud 5. This adjusts the angle of the pressure roller 8. The external thread inside the fastener 7 engages with the internal thread at the top of the stud 5, fixing the adjusted angle of the pressure roller 8. This design accommodates materials of different thicknesses and textures, ensuring a close fit to the material surface, guaranteeing uniform winding, reducing loosening during winding, and preventing winding defects caused by uneven tension, thereby improving product quality. Secondly, in order to prevent the winding roller 21 from being touched by foreign objects during the winding process, the protective baffle 13 can prevent the winding roller 21 from being touched by foreign objects, thereby improving the safety of the winding operation. When the protective baffle 13 needs to be removed when unloading the winding roller 21, the limiting block 12 is pushed upward, which compresses the spring 11 on the sliding rod 10, thereby releasing the installation limit of the protective baffle 13. Thus, the mounting blocks 14 on both sides of the top of the protective baffle 13 can be removed through the mounting groove 9, making it easier to remove the protective baffle 13 when unloading the winding roller 21 and improving convenience.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
